Oh no, it's THAT time again!

The annual triumph of enthusiasm over ability that is the Eurovision Song Contest is with us once again.

Tune in to BBC1 at 8pm on Saturday to witness bizarre bands from small Eastern European countries commit musical murder.

Play spot the transvestite and marvel at the ill-advised dress sense of the Scandinavian competitors.

Split your sides at the largest collection of mullet haircuts seen gathered together in one place these last 20 years.

Chortle as European neighbours play out millennia-old rivalries with the inevitable deployment of the dreaded 'nul points'.

To get you in the mood we have devised two quizzes to test your Eurovision knowledge - one will reveal how much you know about this year's contest and the other is a bracing blast of Eurovision history.

We've also put together a picture gallery giving a flavour of the acts we have known and loved over the years.
